THIS IS A RUSH TRANSCRIPT. THIS COPY MAY NOT BE IN ITS FINAL FORM AND MAY BE UPDATED.

BRIANNA KEILAR, CNN GUEST HOST: Thanks, Jake.

Happening now, fourth suspect -- security services identify a man identified suspected of involvement in last week's attacks. A French newspaper says he was an accomplice of the kosher market gunman and is now on the run.

Al Qaeda's claim -- the terror group says it's responsible for the Paris magazine massacre and says it was masterminded by a U.S.-born cleric.

Terror rivalry -- isn't al Qaeda -- is al Qaeda now competing with ISIS to see who is the deadliest and the most brutal of the global jihadist groups?

And ISIS in America -- an Ohio man arrested for allegedly plotting to attack government targets in Washington in support of the terror group.

Wolf Blitzer is off today.

I'm Brianna Keilar.

You're in THE SITUATION ROOM.

ANNOUNCER: This is CNN breaking news.

KEILAR: Breaking news -- French security services have identified a fourth man suspected of involvement in the Paris attacks. This comes from the newspaper, "Le Parisien," which says the man was an accomplice of kosher market gunman, Amedy Coulibaly. This new suspect is believed to have fled the country.

And in a chilling new development with dangerous implications for the United States, al Qaeda's Yemen branch releases a video saying it's behind the Paris magazine massacre, claiming it was originally masterminded by a U.S.-born cleric who was killed more than three years ago.

Al Qaeda is also applauding the attack on the kosher grocery store and there are new images from inside that market during the bloody siege. We will be breaking those down for you.

Congressman Dutch Ruppersberger, a leading voice on national security, is standing by, along with our correspondents and our analysts.

And we begin in Paris with CNN's John Berman -- John.

JOHN BERMAN, CNN CORRESPONDENT: Brianna, the reason investigators now believe there is a fourth suspect, according "Le Parisien," is because they found keys to a motor scooter inside the apartment of Amedy Coulibaly. Coulibaly is the man who attacked the kosher supermarket. The keys to this scooter -- the scooter did not belong to Coulibaly, it belonged to this fourth man they now believe, according to this newspaper, has left the country.

Now, I spoke to a person close to the security situation here in Paris. He tells me the questions that this report raises are the following.

Could this man have been the man who shot the jogger the day before these Paris attacks?

There was a jogger who was shot. The shell casings matched the ammunition found in Coulibaly's apartment. The jogger, who survived the attack, says she was shot by a white man. Coulibaly, of course, is of African descent.

The other question investigators want to know is who drove Amedy Coulibaly to that kosher market?

How did he get there?

And this security source I spoke to says they're looking into whether this fourth suspect, now believed to be on the run, drove Coulibaly to that market.

Also new today, we have new footage from inside that market as the attack was happening.

(BEGIN VIDEOTAPE)

BERMAN (voice-over): Al Qaeda in the Arabian Peninsula, known as AQAP, is now claiming full responsibility for the "Charlie Hebdo" attack. In this new video, a commander for the extremist group claims the late U.S.-born Muslim clerk, Anwar al-Awlaki, had a role in the attack, which was years in the making.

The al Qaeda affiliate also praises the deadly siege at a kosher grocery store in Paris carried out by Amedy Coulibaly, seen in this just released image wearing what appears to be a camouflage bulletproof vest. These dramatic images captured on security cameras show people huddled together in the aisles, groceries on the floor. The UK's "Daily Mail" says they were taken before the gunman ordered employees to take down surveillance cameras.

Coulibaly, who pledged allegiance to ISIS, was a long time friend of the "Charlie Hebdo" gunmen. AQAP says the attack against the magazine was revenge for the satirical cartoon depiction of the Prophet Muhammad in 2006. The new AQAP video surfaced the same day as the new "Charlie Hebdo" issue hit the newsstands. In Paris, people waited in long, winding lines before the kiosks even opened to get their hands on this new edition. The magazine said it sold all three million copies. More copies are coming.

The controversial new edition again features the Prophet Muhammad on the cover, considered highly offensive by many Muslims.

Security is being stepped up at this newspaper in Turkey, which is publishing the magazine, but not the cover. On Twitter, Turkey's deputy prime minister wrote, "Those who are publishing figures referring to our supreme Prophet are those who disregard the sacred and is an open sedition and provocation."

And today, French officials are digging deeper into the suspects behind last week's terror attacks and searching for potential accomplices still on the loose.

After the attack on the magazine, Said and Cherif Kouachi were involved in a shootout with police before fleeing the scene. And for the first time, we're seeing the Kouachi brothers at a gas station while they were on the run. They were later killed by police.

Sources tell CNN Cherif used his brother's passport to travel to Yemen in 2011, where it is believed he trained with AQAP. U.S. investigators believe the terror group gave Cherif as much as $20,000 to carry out the attacks.

(END VIDEO TAPE)

BERMAN: So many developments in this story. And this reporting of a fourth possible suspect, an accomplice on the run, illustrates exactly why there is this heightened level of security in France right now. Security sources tell me the reason they raised the troop level in the country to 10,000, the police force to 8,000, is because they simply cannot be sure that these accomplices, people who may have known these attackers, may be plotting something else and something new. And that, Brianna, is what they are now guarding against.

KEILAR: All right, John Berman in Paris, thank you so much.

We have more breaking news now. The FBI has arrested an Ohio man for allegedly plotting to attack the U.S. Capitol. We are learning that the suspect identified with ISIS.

But what we've learned is that the Cincinnati man, Christopher Lee Cornell, was allegedly plotting to detonate pipe bombs at the U.S. Capitol and open fire on lawmakers and employees as they ran out of the Capitol Building.

He was arrested today, charged with attempting to kill a U.S. government official. According to the criminal complaint that we are reading through right now, he allegedly aligned with ISIS. He had alarming social media posts that came to the attention of U.S. authorities. The FBI had an undercover informant who was talking with Lee -- with Lee Cornell. And apparently, he told him that he wanted to commit violent jihad, he had been in touch with people overseas, but that he didn't think he would receive authorization to conduct a terrorist attack in the US.

So according to this criminal complaint, he told the undercover informant that we should just wage jihad under our own orders and plan attacks and everything in the name of ISIS.

So as we learn through this criminal complaint, just this week, Brianna, he had taken concrete steps to acquire weapons, semiautomatic rifles, to save money for his plan, to make travel plans. So they had -- officials had enough evidence to be able to make this arrest, build this case. But I'm told by officials that there was no direct threat to the public during the course of the investigation.

KEILAR: They obviously swooped in when they thought things were about to become active.

BROWN: That's right.

KEILAR: OK, we know this is developing right now and you're getting more information as we speak, so we'll hear more from you in the coming hour and change.

BROWN: Perfect. Thank you.

KEILAR: Pamela, thanks so much.

And although their colleagues were massacred just one week ago, staffers at "Charlie Hebdo" put out a new issue today. It sold millions of copies. And on the cover is a new cartoon of the Prophet Muhammad. That's raising new security concerns.

JIM SCIUTTO, CNN CORRESPONDENT: No shortage of demand for that, despite the threats. It started with three million copies. They're going to go up to five million. And I'll tell you, Brianna, it's very hard to find a copy here because of that demand, but also, you have groups inside this country and outside the country, Muslim groups, Muslim governments in the Middle East, still expressing outrage here. And that is also helping to feed some of the concern, the genuine concern from French authorities about further reprisal attacks. I'll tell you, the president of France, Francois Hollande, announced today that plans to reduce the police presence in the country this week, to ratchet it down ever so slightly, are being shelved. They're thinking of keeping these numbers they've have had, 8,000 to 10,000 police and soldiers around the country at this level, in part, because of that threat.

KEILAR: Yes, a very visual heightened state of alert there.

All right, thank you, Jim Sciutto in Paris.

Appreciate it.

If al Qaeda in Yemen was responsible for the massacre and intelligence agencies were blind to the development of that plot, it may have frightening repercussions for the United States.

Let's turn now to CNN Pentagon correspondent.

Barbara Starr.

This would be significant if this was completely missed -- Barbara.

BARBARA STARR, CNN CORRESPONDENT: Good evening, Brianna.

Absolutely. U.S. officials sketching out for CNN one of their biggest worries about all of this.

U.S. and French intelligence services are urgently working to determine if al Qaeda in Yemen, AQAP, secretly communicated with the Kouachi brothers after one or both of them returned from Yemen in 2011. If that communication happened, it was so secret, it wasn't detected, despite the vast eavesdropping capabilities of the US.

And that means the number one al Qaeda terrorist organization targeting the U.S. and threatening to bomb aircraft can plot and plan without the U.S. knowing about it.

MARIE HARF, DEPUTY STATE DEPARTMENT SPOKESWOMAN: AQAP is the most dangerous affiliate associated with Al-Qaeda core, particularly in terms of external plotting outside of their region where they are located.

STARR: It remains possible the Paris attackers had no direct orders from AQAP. But the U.S. believes that al Qaeda in Yemen is now using advanced encryption technology as just one method to keep their operation secret from U.S. spying. That alone gives AQAP huge room to maneuver.

THOMAS SANDERSON, CSIS: They could have seeded parts of Europe and other parts of the world with these individuals who have been trained and instructed to attack when they feel appropriate, or they could have an ongoing cadre of individuals that come in and out of Yemen and set them off at a time of AQAP's choosing.

STARR: The U.S. calculates AQAP was already on the upswing in power for many reasons. Senior leaders like Nasir al-Wuhaysi and master bomb maker, Ibrahim al-Asiri, are all in secure locations in Yemen, all still very much in charge.

Its safe haven areas are large and secure. It's continuing to recruit foreign fighters. All of this raising questions about whether U.S. drone attacks in recent years have even made a dent in the group.

SANDERSON: No one expected drones to have suffocated AQAP and put it out of business.

(END VIDEO TAPE)

STARR: And this gets back to what we've all been talking about, the real implication now, not just Paris, but is AQAP planning additional attacks and can the U.S. detect them -- Brianna.

KEILAR: Barbara Starr at the Pentagon, thank you.

And now more on this breaking news coming into THE SITUATION ROOM.

Joining me right now, we have Democratic Congressman Dutch Ruppersberger of Maryland, a key vote on national security issues. He was the ranking Democrat on the Intel Committee when the U.S. killed American-born cleric Anwar al-Awlaki.

So, thank you so much for being with us, Congressman.

REP. DUTCH RUPPERSBERGER (D), MARYLAND: Sure.

KEILAR: I want to talk to you about this fourth suspect that has now been identified.

Are you thinking that this will go beyond a fourth suspect?

Could we see a fifth, a sixth suspect?

RUPPERSBERGER: Well, the fourth suspect, who is an individual they were trying to target, but more importantly, it's the leadership in Yemen. This clearly -- and it's been verified that this was an attack done in Paris by the Arabian Peninsula al Qaeda. This is -- this group is a lot different than the ones that we were dealing with in Afghanistan and Pakistan.

Why they were different, it's an American cleric, who, fortunately, we were able to bring to justice and he's no longer with us, al-Awlaki. And his strategy was to have attacks that were low key. You've heard of lone wolf, but smaller groups, so that we and the United States and our allies would not pick up the intelligence.

KEILAR: More decentralized... RUPPERSBERGER: Right.

KEILAR: -- less micromanaging from the leadership.

RUPPERSBERGER: The 9/11 attack is very difficult because we're going to probably going to get the information. And yet the Awlaki strategy -- he was the one who planned the underwear bomber, the shoe bomber -- trying to come under the wavelength. And that concerns us all in the intelligence community.

And that is one of our biggest threats that we're dealing with.

And this is why we were so concerned about Snowden, the person who turned his back on the United States, because when he put out information, he said to the world, these are our sources and methods. This is what the United States does to collect intelligence.

So we have lost a lot of those terrorists that we had acknowledged that we had acknowledged that we had discovered. And they know now not to do the things that we need to do so they could be detected.

KEILAR: Well, let me ask you about that. If al -- and I know part of it is the strategy is maybe train, maybe finance, but then sort of let loose of some of these trainees so that they can fly under the radar.

But at the same time, if you had communication between the Kouachi brothers and AQAP, what does that say, that intelligence didn't pick it up in a way that they realized when a threat it was?

RUPPERSBERGER: What it says is that they have learned our techniques. Our sources and methods. That's why in the intelligence arena, when things are classified, so our enemies don't understand what we do to get information to protect our citizens. That's what it really says.

And now, let's talk about the United States, because in the end that's what we're trying to protect. We know there are many sympathizers in the United States, and we know that there are people that go to Syria from the United States to be radicalized.

There was a situation where we had an individual that went to be trained. He was from the United States, went to be trained in Syria, to be a suicide bomber. Why he would want to give up his life, but he did. Came back home to visit his parents, then left and went back to Syria and blew himself up and killed people. That individual could have had an attack or a suicide bomb situation in the United States.

The best defense against terrorism is intelligence. Not only from a point of view with the United States but all of our allies. The more intelligence we get, the better.

But this is serious and I'm also worried about the issue between al Qaeda and then ISIS. It's almost -- I'm concerned they want to compete against each other. And now they have this successful attack that the other might try to be more aggressive. And the ultimate target will be the United States of America. KEILAR: All right. Stick with me, because I want to get a little

more out of this conversation. But we've got to get a quick break in. We'll be right back with ore on this.

(COMMERCIAL BREAK)

KEILAR: Our breaking news, French security services have identified a fourth man suspected of involvement in the Paris attacks. The newspaper, "Le Parisien," says the man was an accomplice of kosher market gunman Amedy Coulibaly. The new suspect is believed to have fled France, and this comes as al Qaeda's Yemen branch claims responsibility for the attack on the "Charlie Hebdo" magazine offices.

We're back now with Democratic Congressman Dutch Ruppersberger of Maryland, a key voice on intelligence and national security issues.

And I think one of the things, Congressman, that may be alarming to people, this is really just developing, I have to say, news that in Ohio, here in the U.S., an ISIS supporter was planning an attack on the U.S. Capitol. I know this is -- you haven't been briefed on this.

RUPPERSBERGER: Brand new. Haven't been briefed, but there's an example of sympathizers. There are many sympathizers, I'm sure, in the United States. And that's why we need intelligence to find out people that are actually plotting and planning.

There's not -- the al Qaeda from Yemen is not going to be able to come to the United States one day and show up and do the attacks. They need help. They need to do research. If, in fact, the facts are as we know them now, this attack has been planned for the last two to three years. So we have to be concerned about sympathizers, and this is why it's a federal, state and local issue. We have to have citizens in our country, if they see something unusual, let your law enforcement know.

KEILAR: What are you -- what were you talking about when you're seeing something unusual. You gave an example of people moving into a house and coming and going and suspicious activity.

RUPPERSBERGER: You have somebody running a house with four or five people coming in, but it just depends on the situation. One little tip can make a difference. It's just that we need to gain intelligence, and a lot of intelligence comes from people. It's not only technical intelligence. It's people intelligence.

KEILAR: OK. And then it sounds like you are pretty convinced, because there is this claim by AQAP that they're the ones responsible for the "Charlie Hebdo," at least, not the kosher market attack. And then we know from one of the Kouachi brothers, he told a media outlet in France that it's AQAP that he was working with. So you ultimately think this is the mark of AQAP?

RUPPERSBERGER: I think AQAP is a lot more dangerous to the United States, Awlaki was an American citizen and really ran AQAP in Yemen. And I have been to Yemen and seeing what goes on and how they train people there.

The bottom line is that his focus was the United States. We were lucky that the shoe bomber didn't go off, the underwear bomber, but his strategy was to have a small group of people attack the United States, and finally, his strategy worked in France, unfortunately. We have to be aware of that. The lone wolf, the smaller attacker. That's his style.

KEILAR: Do you think there are U.S. sleeper cells here?

RUPPERSBERGER: If I do, I probably couldn't tell you but I don't believe they're sleeper cells as much as they're -- they're people who want to support some of the al Qaeda and what they believe in, unfortunately. That's my concern.

And that's why again, intelligence is the best defense against terrorism. In the United States of America, Americans are not being spied on at all by our government unless there's a court order; and yet we need to know and look at the threats that are there.

We've talked about threats for years, that these threats are getting more aggressive right now. So we have to be vigilant, and we will.

KEILAR: OK. Let's listen...

RUPPERSBERGER: We have a great country, and we have the best intelligence in the world.

KEILAR: Let's listen to something President Obama said in September on why the air campaign in Syria could destroy ISIS.

(BEGIN VIDEO CLIP)

BARACK OBAMA, PRESIDENT OF THE UNITED STATES: The strategy of taking out terrorists who threaten us while supporting partners on the front lines is one that we have successfully pursued in Yemen and Somalia for years.

(END VIDEO CLIP)

KEILAR: Was it a mistake to call Yemen a success?

RUPPERSBERGER: I think you have to look at the facts as they are. I think what we did as far as going after ISIS is that we stopped their momentum, but that's just the beginning.

You know, we have to be the supporters of the whole Arab world, the whole Middle East. We have to stand up to this situation. We in the United States of America have been through Iraq, and we've been through the other areas in Afghanistan. We don't want to go another ten years of war and put our men and women on the line. But what we do...

KEILAR: And so there was momentum in the right direction in Yemen, and now that's been pulled back? RUPPERSBERGER: Well, first thing, I think what the president was

saying, if you want to take out a -- I hate to say it this way, but you want to kill the snake, you have to cut its head off. And that's what you do. That's the focus of leadership of al Qaeda.

When you take out their leadership, they're weakened by that. The command and control. But now that ISIS has been around, al Qaeda has been around, they have a lot of leadership. They have money now. They have people who have researched, and these are the things that we also have to deal with.

But the United States can't be the sheriff of the whole world, but we have great resources. We're trying to coordinate all of the countries over there, the Arab countries, to stand up to this threat and have them be involved with boots on the ground and let us support them.

KEILAR: Congressman Ruppersberger, thanks so much. Thanks for being here.

Next, a closer look at one of the most alarming new threats to global security. The growing rivalry between al Qaeda and ISIS.

Now, we're also-- we have some new video to show you. This is from the bottom of the Java Sea, where searchers finally have located the fuselage of the AirAsia jet.

(COMMERCIAL BREAK)

KEILAR: Our breaking news, French security services have identified a fourth man suspected of involvement in the Paris attacks. This is from the newspaper "Le Parisien," which says the man was an accomplice of kosher market gunman Amedy Coulibaly.

BRIAN TODD, CNN CORRESPONDENT: Brianna, tonight we are getting chilling new information from counterterrorism officials about how al Qaeda and ISIS are competing and what the consequences could be.

What one House Intelligence Committee member now calls a dangerous competition among terrorist groups to capture the world's attention and attract followers.

(BEGIN VIDEOTAPE)

TODD (voice-over): A chest-thumping from one of al Qaeda's most dangerous branches over the "Charlie Hebdo" killings, paying tribute to the Kouachi brothers, al Qaeda in the Arabian Peninsula says its leadership chose the target, planned and paid for the attack.

NASR IBN ALI AL-ANSI, COMMANDER, AQAP (through translator): When the heroes were assigned they accepted. They promised and fulfilled.

TODD: It's not clear how much of that is bluster, how much of a hand AQAP really had in the slaughter in Paris. What is clear to experts: this group has regained its momentum.

KATHERINE ZIMMERMAN, AMERICAN ENTERPRISE INSTITUTE: AQAP's status is once again reaffirmed to be at the top, if not on top of the global jihadist movement.

TODD: Now other top terror groups are lining up to praise the Paris attack, ISIS and Boko Haram among them.

TODD: Tonight, CNN has learned of a chilling new concern among U.S. counterterror officials: that there's fresh intensified competition among the most dangerous terror groups to one-up each other, to take back the spotlight.

ZIMMERMAN: Who can hit hardest, who can show that they're fighting the hardest, and who can actually prove that their strategy is successful?

TODD: A competition seen primarily between AQAP and ISIS. For the better part of two years, ISIS seemed to dominate, capturing huge swaths of territory in Syria and Iraq, beheading five westerners on TV. But counterterror officials and analysts tell CNN it's AQAP's capabilities to strike outside its neighborhood that concern them.

ZIMMERMAN: AQAP is certainly oriented on attacking the United States and much more so than we've seen come out of ISIS.

TODD: Evidenced by the 2009 underwear bomb attempt on a U.S.-bound airliner. And AQAP's plot to place bombs in printer cartridges being flown to the U.S. All the work of its master bomb maker, Ibrahim al- Asiri, who's still at large.

ISIS isn't letting up, releasing a new video that appears to show a boy executing two men. But the Paris attack ratchets up the pressure on ISIS.

MATTHEW LEVITT, WASHINGTON INSTITUTE FOR NEAR EAST POLICY: ISIS needs to compete, not only, say, on the ground in Syria and Iraq, but for opinion and funding and recruits within the global jihadi community, also by carrying out attacks abroad, maybe this radicalizes it to do that.

(END VIDEOTAPE)

TODD: Who is winning the competition for recruits? The lifeblood of these groups? A U.S. counterterrorism official tells us ISIS is still drawing more foreign fighters than AQAP. The official calls Syria their destination of choice. And we know that Hayat Boumeddiene, the girlfriend of one of the Paris gunmen, has likely just arrived in Syria, drawing concern about what she may do next -- Brianna. KEILAR: And Brian, I want to ask you about the very dangerous leaders

of AQAP. What can you tell us about them?

TODD: That's right. The top leader of AQAP, his name is Nasir al- Wuhayshi, plus the bomb maker, the master bomb maker, Ibrahim al- Asiri. A U.S. official tells us they are both believed to be still alive in hiding somewhere in Yemen. And the bomb maker, al-Asiri, particularly dangerous, Brianna. He hatched those plots against America, and U.S. officials tell us he has trained others. But the question is, where are they and where are they going.

KEILAR: All right. Brian Todd, thanks so much.

And I want to take now a closer look at this newly-released video of the Paris supermarket siege. These came out just this evening. And these are pictures of the gunman and his hostages revealing, I think, a lot more than you might think.

I'm joined now by former FBI assistant director Tom Fuentes. He is a CNN law enforcement analyst.

We've been looking at those photos, Tom. I want to look at this one, because it really tells a story. This is -- you can see the chaos of the groceries scattered about, and then so grim and heartbreaking, you see this is one of the victims. And this is a 22-year-old who's very significant for what he tried to do.

TOM FUENTES, CNN LAW ENFORCEMENT ANALYST: Well, we're told that Coulibaly set his gun down, the long gun, the rifle, on the countertop here, and he tried to take that gun and turn it on Coulibaly, and apparently, it jammed. At least they reported that it jammed. Or he just didn't know how to operate it. Maybe it was on safety, and he didn't know how to deal with that. But he ends up being killed as a result of that. Coulibaly has a hand gun with him also and is able to stop them.

What's interesting about that is that the AK-47, which has been the weapon of choice by these guys, there's 100 million in circulation now since 1949, and it's so popular among terrorists because it almost is jam-proof. They can take it in the desert. They can shoot it in the sand. And so it's kind of surprising to me that the gun would jam as opposed to he just didn't know how to operate it properly.

KEILAR: Yes, OK. So maybe that is the case. And a 22-year-old who is trying to rescue the people in this kosher market. This photo, I will tell you, struck me, because this is a stroller abandoned here. We know there was a 2-year-old in the basement freezer, hiding out with adults. It makes you wonder if this wasn't that kid's stroller.

And then I want you to look here. This is another view from this closed-circuit television of a number of hostages. I counted eight, eight or nine here, I think. What are they doing, do you think?

FUENTES: It appears that they're being lectured to somehow, that they've been gathered. And maybe warned or maybe he's issuing, you know, a statement to them that, "If you act up, I'm going to kill you," or you know, something. But it just appears that they're not -- you know, looking down the barrel of a gun, but they appear to be paying attention of some kind, being told something.

KEILAR: OK. And stay with me, Tom, because coming up, we are going to discuss this photo. It is a picture of what appears to be Coulibaly himself, forcing a hostage to lock the back door. We see him here with what appears to be his weapon. We have a number of other photos we'll be looking at with you, Tom Fuentes.

And coming up, we have more on the breaking news, a fourth suspect identified in the Paris terror attacks.

Also, found at last, the fuselage of the AirAsia jet lying on its side at the bottom of the Java Sea. But as one mystery is solved, many more are created.

(COMMERCIAL BREAK)

KEILAR: We are following breaking news now. The French newspaper "Le Parisien" reports security services have identified another suspect, an accomplice in the Paris terror attacks, and that that man is still at large.

With us now in THE SITUATION ROOM to talk about this, we have former congressman, Mike Rogers. He was chairman of the House Intelligence Committee, now is a CNN national security commentator. We have Bob Baer. He's a former CIA operative and CNN national security analyst. We have CNN law enforcement analyst Tom Fuentes still with us. And joining us from Paris, we have Guillaume Debre. He's a correspondent for the French television channel TF-1.

Guillaume, to start with you, we have this report of another suspect, an accomplice here who may have been responsible for the shooting of a jogger the night before the "Charlie Hebdo" attack. What can you tell us about it?

GUILLAUME DEBRE, CORRESPONDENT, TF-1: Well, I can tell you that investigators have a name. They haven't -- they don't want to release it, they don't want to talk about it, but they know that it's a white male. They don't know whether it's Caucasian or Arabic, but it's not a black man that pulled the trigger on Thursday night, shot a jogger with the similar gun, the same gun that was found at this Jewish grocery where Amedy Coulibaly did his massacre on a Friday night. They are actively looking for this man.

There is a number of suspects they're now chasing. What they're really interested is the key. They found the key of a motorbike on Amedy Coulibaly's body when he was shot. They want to try to find this motorbike. They've located it, and they want to know who it belongs to; and they want to know exactly; who took or drove Amedy Coulibaly to the grocery store. They actually suspect that there are not just one or two associates, but there are a lot more. They don't want to be specific on the number, but I think there's a lot more associated than one or two.

KEILAR: A lot more, so much more to find out here. Bob, I wonder, you have AQAP taking responsibility for this attack,

but then Coulibaly, the alleged killer in the kosher market attack, pledged allegiance to ISIS. What's going on here?

ROBERT BAER, CNN NATIONAL SECURITY ANALYST: Well, I mean, I think that ISIS and al Qaeda share the same objectives and that's to attack the West. They have different strategies. Islamic State wants to set up a government first and then expand, and al Qaeda wants to attack abroad.

So it doesn't really surprise me that they cooperated at the ground level but what's important is that in the tape today by the head of AQAP, he marginalized the Islamic State so there's clearly a rivalry. And I agree with intelligence analysts, there is going to be a competition to take the fight abroad as well as in Syria and Iraq.

KEILAR: Chairman, how concerning is that to you, that there is this rivalry? What does this mean?

MIKE ROGERS, CNN NATIONAL SECURITY COMMENTATOR: Well, we have watched this develop over about the last 12 months and it was not just for people and recruits, because ISIS is winning that hands down, but people who are showing up to fight in Syria are a little different than what al Qaeda was looking for to pull off operations overseas. And so you see a very unhealthy competition that has been long in the making.

Even inside Syria, there was fighting between ISIS -- alleged people who had allegiance to ISIS and al Qaeda affiliates, Al-Nusra and Elshaab. Both of those groups had shooting matches, if you will, in Syria over control of certain pieces of land and materials and as well as resources. So we've seen this developing for some time. What's concerning is that both have a desire in their minds to put points on the board by having a successful attack both in places like Europe and the United States.

KEILAR: So they have, though, a common enemy at least in some cases when they are enemies with each other. How likely could it be that we might see AQAP and ISIS either coordinating on some of these things or that they could do that in the future?

TOM FUENTES, CNN LAW ENFORCEMENT ANALYST: I think there'll still be at the bottom level some coordination. You know, the enemy of my enemy type reasoning, but the dangerous factor with Al Qaeda in the Arabian Peninsula is we still have not seen evidence of al-Asiri's bomb making and that's the scariest part about them.

Their ability to move PETN, a principal explosive in the underwear bomb, in the printer cartridge bomb plot of 2010, and that plot was foiled because Saudi intelligence had penetrated that plot, were able to provide shipping numbers to British and American authorities. So in these various cells here in France, we haven't found PETN yet. It makes you wonder is that coming later, where is that?

KEILAR: All right. Gentlemen, thank you so much. Chairman Rogers, Tom Fuentes, and Guillaume Debre, joining us, as well as Bob Baer. We have a whole lot more on today's developments in the wake of the

Paris terror attacks. At the top of the hour we are going to get an update on al Qaeda's claim of responsibility and the urgent U.S. efforts to head off new attacks from the complicated and expanding jihadi network.

But next, today's grim discovery in the search for the crashed AirAsia jet.

(COMMERCIAL BREAK)

KEILAR: We have much more coming up on the breaking news in Paris terror attacks, including word the French are looking for yet another terror suspect. We're also covering important developments in the AirAsia crash investigation. Searchers finally located the jet's fuselage.

CNN aviation correspondent Rene Marsh is here with details.

This is key. This is a huge piece of the plane.

RENE MARSH, CNN AVIATION CORRESPONDENT: Especially for the families. And now if most of the bodies are in the fuselage, I would expect that divers would go in to try and bring these bodies to the surface. Of course, the seas have been rough at times. And that could delay efforts. But just in a matter of hours that search for more bodies begins.

(BEGIN VIDEOTAPE)

MARSH (voice-over): The fuselage of AirAsia Flight 8501 finally located below the surface of the Java Sea. The more than 100 missing bodies may be entombed there. Setting up what could be another tidal wave of emotions for victims' families.

BAMBANG SOELISTYO, INDONESIAN SEARCH AND RESCUE AGENCY (Through Translator): We found part of the airplane body or what we call the fuselage with one of the wings still attached.

MARSH: Underwater robots found the wreckage. You can see part of the airline slogan, "Now Everyone Can Fly," and a section of the wing with the plane's registration number on it.

MARSH: Alan Diehl, who survived a plane crash himself has written about his 40 years as an accident investigator.

DIEHL: The wreckage provides evidence on what failed on the aircraft and it will also give some strong clues as to why. It will talk to us about the sequence of the breakup and just exactly what failed aboard the aircraft.

MARSH: The fuselage, the largest piece of wreckage discovered yet, is nearly 100 feet long. It's 25 feet shy of the entire length of the Airbus A320. It was found nearly two miles northeast of the tail and about a half a mile from the flight recorders.

DIEHL: The Flight Data Recorder tells you what happened. But you have to listen very carefully to the cockpit voice recorder to find out why it happened.

MARSH: Today, the Cockpit Voice Recorder was dried out and downloaded. Investigators who are also pilots listened to it for the first time. They won't say what they heard. A full analysis could take months.

(END VIDEOTAPE)

MARSH: Well, investigators will sit down with people who've flown with these pilots, people who know them and can identify their voices on the recordings. They will play and replay the recordings over and over again to compare it. They'll also compare that information to the information on the data recorder and that's how they begin sketching out the scenario that played out on December 28th -- Brianna.

KEILAR: Yes. Good news for the families. Not that there can really be good news at this point, but maybe some closure to put their loved ones to rest.

All right, Rene Marsh. Thank you so much.

Coming up, ISIS in America. An Ohio man is arrested for allegedly plotting to attack the U.S. capitol in support of the terror group.

(COMMERCIAL BREAK)

KEILAR: Happening now, breaking news. New terror suspect. French investigators reportedly identify another man involved in the Paris attacks. Who is he? And where is he now?

Al Qaeda claim. The group's affiliate in Yemen says it's responsible for the attack on the magazine "Charlie Hebdo." Were there missed signals as the terrorists communicated with each other.
